Figure 2.

Mirror-biting behavior endpoint comparisons between the AB zebrafish (white), absolute zebrafish (red), TL (Tübingen Long Fin) zebrafish (blue), golden zebrafish (green), PET (Pet Store-purchased) zebrafish (purple), and the WIK (Wild Indian Karyotype) zebrafish (orange). (A) Mirror-biting time percentage and (B) the longest duration in the mirror side percentage were analyzed for the mirror-biting assay. The median and the interquartile for the violin plot were labeled with the bold line colored with cyan and yellow, respectively. The 5 min locomotor trajectories for the AB, absolute, TL, golden, and the WIK zebrafishes are presented in (C–G), respectively, with the yellow-colored zone as the mirror-biting region. The data were analyzed by a Mann–Whitney test (n = 30 for each group, except for the WIK zebrafish (n = 23); ** p < 0.01; **** p < 0.0001).
